A wooden fossil, which shows the geological history of Korea, is well preserved as a natural monument in Moran Hill of Pyongyang. The Moranbong dendrolite fossil in the vicinity of the Chongnyu Cliff, which was the tree growing by a lakeside in the Early Jurassic Epoch of the Mesozoic era, the geological age of about 200 to 175 million years ago, was buried by the geological action, and the silicon component dissolved in underground water filled the gaps of its cells.
The fossil was the gymnosperm which grew thickly at that time. Originally, the spot was covered in petrified forest of upright or fallen petrified trees. This tells that the climate of those days was a subtropical one, and that tall trees made a forest in the area.
Various plant phytolith such as bracken and cycad species came from the layers which are almost similar to the tree fossil layer.
According to paleontologists' research findings, this tree fossil is a type of pine tree.
The annual ring of the fossil and the structure of its cells serve as important data for studying paleoecological environment of the Early Jurassic Epoch of the Mesozoic era.
